论文摘要
在此手稿中，研究了在网格连接模式下超级电容器燃料电池的性能。用三级双向DC-DC转换器实现了对超光速器的电压调节，同时还通过双向转换器实现了从网格到Ultra-CapaCitor的功率流。双向三级转换器用于电压调节的选择是基于其固有的高效率，低谐波轮廓和紧凑的大小。使用使用开关函数方法得出的转换器和网格连接的逆变器的模型方程，分别在MATLAB中分别模拟了网格的直接和正交轴调制指数MD和MQ，用于滞后和领先的功率因子。此外，在基于PLEC的模拟中利用了MD和MQ的值，以确定功率因数校正对电流的电流和功率注入对电网的影响
In this manuscript, the performance of an ultracapacitor fuel cell in grid connected mode is investigated. Voltage regulation to the ultracapacitor was achieved with a three level bidirectional DC-DC converter while also achieving power flow from the grid to the ultra-capacitor via the bidirectional converter. The choice of a bidirectional three level converter for voltage regulation is based on its inherently high efficiency, low harmonic profile and compact size. Using the model equations of the converter and grid connected inverter derived using the switching function approach, the grid's direct and quadrature axes modulation indices, Md and Mq, respectively were simulated in Matlab for both lagging and leading power factors. Moreover, the values of Md and Mq were exploited in a PLECS based simulation of the proposed model to determine the effect of power factor correction on the current and power injection to grid
